An MPLS Circuit is a virtual private network (VPN) for securely connecting two or more locations over the public Internet or a private MPLS VPN network. MPLS circuits are secured through encryption on a customers router, which is known as a CPE based MPLS VPN, or on the MPLS providers network router, which is known as a network-based MPLS VPN. MPLS circuits are typically provisioned over dedicated Internet lines or a private MPLS VPN circuit, with options for managed MPLS circuit services. An MPLS network provides class of service (CoS) by utilizing MPLS VPN technology to prioritize and route time-sensitive data based on application type. MPLS circuits are used by businesses to provide a reliable, secure, data network for applications including credit card processing, file sharing, data backup, VOIP, video, or remote access. MPLS circuits can also be configured by most providers to carry voice, Internet, and IP VPN services together as an Integrated MPLS line. MPLS circuit services are also known as an MPLS Network, MPLS VPN, or MPLS WAN.
